The renovation process in an apartment includes a lot of work related to creating holes in the walls: a tool can be used for this various designs and power. Many craftsmen and those who are planning to carry out repairs themselves want to know how to drill concrete wall with a regular drill and is it even possible? For such work, a hammer drill is usually used, but it is not always suitable for this; moreover, if you have to buy a tool, then its cost is much higher than that of a drill.
Features of choosing a tool
In most cases, it is better to use a hammer drill: it has increased power, is designed for punching hard surfaces, and allows you to make large-diameter holes. The use of the tool is inappropriate in the following cases:
- the need to drill the wall to a depth of 10-12 mm;
- working with, which crumbles when processed with a hammer drill;
- the work requires making no more than 10-15 holes.
Before drilling a wall, it is important to choose the drill itself: it should not be impactless, since this type is ineffective when drilling concrete; the attachment and chuck almost immediately become unusable. The nozzles themselves must be victorious, designed for concrete works, tip - with carbide coating.
In some cases a good decision you will purchase a hammer drill: the device is more expensive than the classic model, but has increased power, which can be adjusted.
Which attachments to choose?
Before drilling a hole in a concrete wall, you need to select a nozzle of the appropriate design. The following types are used for work:
- Impact-type toothed bits designed for drilling. When working with concrete, it is recommended to use varieties made from individual soldering teeth, made from the most durable metal alloys. Many bits are equipped with SDS tails for installation in a drill with a keyless chuck. Drills are well suited for concrete walls, however, upon contact with metal they can begin to collapse, so before drilling into a reinforced concrete wall, you need to check that there is no reinforcement used for reinforcement at the work site.
- Diamond bits, which are designed for hammerless drilling of holes. Such nozzles are more modern; with their help, it is easier to make a hole in a concrete wall. The edge of the crowns has an abrasive structure and special cutouts; during production it is processed by spraying diamond chips or corundum. Before making a hole in the wall, you only need to select the desired length of the nozzle: in everyday life, varieties with a diameter of up to 100-120 mm are used, in professional work larger crowns are used. Distinctive feature is the ability to drill without the risk of damaging the fixture with fittings.
- KS-crowns, which have a cutting edge with crystalline diamond particles. Such nozzles are used for most solid walls, including drilling with them. concrete plates, external walls and stone structures.
Before drilling or partitioning, you need to make sure that wires or cables, if any, will not be touched during the work.
How to drill concrete with a drill?
Typically, such work is performed in the following cases:
- rough finishing of premises;
- installation of built-in furniture and appliances;
- installation of wiring and plumbing when communications need to be concreted.
When using a Pobedit nozzle during work, it is necessary from time to time to use a metal punch, which is selected to match the size of the hole being formed. This tool allows the drill not to jam when the drill is deeply immersed: the punch is placed in the concrete and deepened with hammer blows to make a hole in the wall, destroying the seal.
This process is quite long; an alternative is to use diamond bits: a drill equipped with such attachments will not get stuck in concrete.
Algorithm of actions:
- Before drilling a hole in the wall, you need to install the desired nozzle, after making sure that the tool is in good working order and the drill is intact.
- Drilling concrete must be done carefully; when using low-power equipment, the duration of continuous operation of the drill should not be more than 10-12 minutes. If drilling takes a long time, you need to take breaks so that the device’s motor cools down.
- Once it has become clear to drill a concrete wall, it is also worth considering that for each new hole it is necessary to process the nozzle. You can moisten the surface with water to facilitate the procedure and protect the metal from deformation.
The whole process of work can be seen in the video:
If you encounter a stuck drill, do not remove it by force: this will lead to the device breaking off, resulting in the tip remaining in the concrete. You need to disconnect the nozzle, select a crown of reduced diameter and use it to pull out the stuck element.
Before deciding what to drill into concrete walls and starting work, you should pay attention to the following recommendations:
- if the hole diameter exceeds 12 mm and the depth is 10-11 cm, it is better to use a hammer drill or a hybrid device (drill-hammer);
- if holes are made for plastic dowels, the depth should be larger size fastening element by 7-10 mm, since concrete dust and small particles of stone remain inside;
- It is recommended to start work at low speeds so that the nozzle does not move due to increased torque, and the impact mode is turned on when the drill passes 2-4 mm in depth;
- dust that appears during the drilling process can be removed with a vacuum cleaner; it is advisable to do this during the process, periodically stopping the drill and cleaning the hole from concrete particles;
- Be sure to follow safety precautions during work: you need to wear gloves to eliminate the risk of the handle slipping and safety glasses to prevent crumbs from getting into your eyes and damaging the mucous membranes.
In most cases, a concrete wall is drilled with a hammer drill, without a drill. If, as part of the repair, you need to make no more than 15-20 holes or the wall is made of foam concrete, using a drill is optimal choice which will save time and money.
Before punching a hole, you need to make sure that there is no wiring in this place, and check whether the attachment is suitable for such work (the duration and efficiency of the work depends on what kind of drill the drill is equipped with). When deciding how to drill a wall, you should pay attention to pobedite bits: with such a drill using a drill, you can easily make a hole up to 10-12 cm deep.
The ability to drill holes in concrete is a fairly useful and convenient skill. With it, you can easily hang shelves, hang pictures, install lamps and do a lot more work around the house quickly and safely. The process of drilling concrete is quite simple, but with correct selection tools and understanding the principles of operation you will save yourself a huge amount of time.
Steps
Part 1
Preparing for work- Follow safety precautions. This includes wearing safety glasses to prevent concrete chips from getting into your eyes, using earplugs to protect your hearing, and thick work gloves to protect your hands from increased friction and hot drill bits. For long work where there is a lot of dust, it is also recommended to wear a respirator.
-
Insert a high-quality concrete drill bit into the tool. Carbide tipped concrete drill bits (or “percussion bits” as the packaging may indicate) are specifically designed for impact drills and can withstand the stress of impact drilling into strong concrete. The length of the fluted drill bit should be no less than the depth of the hole you are going to drill, as these flutes are important for removing generated dust from the hole.
Adjust the drilling depth. Some drills have the ability to adjust the drilling depth or a special limiter. Read the tool's user manual to learn how to use it. If your machine does not have a drill depth stop, measure and mark with a pencil or masking tape required depth holes on the drill itself. If you are unsure about the depth of holes you need, follow the guidelines below.
Hold the drill correctly. Hold the drill with one hand like a pistol, resting forefinger to the start button. If your drill has an extra handle, use your other hand to hold it for a more secure grip. Otherwise, simply grab the drill from below with your other hand, closer to the back of the body.
Buy or rent an impact drill. Drilling holes in concrete is easier impact drill or a hammer drill (in case of large works). These tools will allow you to crush concrete with reciprocating blows of the drill and extract the resulting crumbs by rotating it. Doing this type of work with a conventional drill will be slow and difficult, since concrete does not drill as easily as wood or metal. For any job that will involve more than drilling a few holes in decorative (rather than structural) concrete surfaces, such as modern softer ones kitchen countertops made of stone chips, don’t skimp on paying a little more to rent a percussion instrument.
Learn the tool. Read the owner's manual and memorize the functions of all buttons and switches on the instrument. You should have a good understanding of how to handle the tool before moving on to the next step.
Part 2
Drilling concrete-
Continue drilling, but with more force. Switch to impact mode (if your drill has one). Place the drill on the basting hole strictly perpendicular to the concrete surface. Start drilling again using firm, but not excessive, pressure on the drill until the drill bit begins to sink into the concrete. Gradually increase the rotation speed of the drill and the pressure on it if necessary, but remember that the drill must remain under your full control and in a stable position at all times. Concrete is quite heterogeneous and the drill can easily slip if it hits an air pocket or void.
- Apply enough pressure to the drill to keep it in position, but do not push it forward too much (this increases wear on the drill and may cause it to break). You will understand how hard to press the drill from your own practical experience.
Mark the point for drilling the hole. Using a soft pencil, place a mark on the wall in the form of a dot or cross in the place where you want to drill a hole.
Drill a pilot hole. Place the drill bit against the mark and briefly run it at slow speed (if your device has an adjustable speed) or make a few short presses on the start button (if there is no speed adjustment). You should be left with a 3-6mm indentation that will help you guide the drill correctly when drilling the main hole.
Small renovation work periodically become a necessity in every home. Drilling was no exception. To implement it correctly, you need tools, experience and a little time, otherwise it will be an unwanted expenditure of money. To avoid the latter, we have prepared for you an article on the topic: “How and with what to drill into a concrete wall?” Let's look at all the important points.
How to drill into a concrete wall
New or old tool
Remember, if your wife asks: “How to drill a hole in the wall to install an outlet there?”, then it’s time to resort to using a hammer drill!
Additional Information
To prepare the wall for drilling a hole large diameter Make a small notch in the center of the mark with a thin drill. This will allow you to later find a comfortable stop with the tool so that it does not slip off. You need to press the drill moderately, without applying significant force, otherwise there is a risk of breaking the drill.
Periodically blow dust out of the hole, this will increase the reliability of the fasteners being installed. A rubber bulb or a can of compressed air is suitable for this. Blowing with your mouth is not recommended, as dust will get on your face and eyes (as a last resort, use safety glasses).
We hope our information resource helped you, and the question of how to drill concrete no longer bothers you. Good luck!
During repairs, communications or redevelopment, it becomes necessary to carry out different quantity holes in the walls. The tool and drilling technique will vary depending on the wall material. Before drilling into a brick wall, it is recommended to use some practical advice, since such a durable material as brick sometimes requires a special approach.
The wrong choice of tool and type of drill will not only not allow you to get the desired result, but can also damage the equipment. To drill bricks, two types of equipment are used - a hammer drill or an impact drill. Right choice drill, first of all, lies in its power. The minimum power of this tool must be no less than 600 watts, and the minimum number of revolutions must be from 2500 rpm. It is better if the mechanism has reverse rotation of the drill and the ability to smoothly adjust the power. Drilling holes in brick should be done with an impact drill, since walls made of this material are very durable. static loads, and are subject only to shock with a dynamic load. If you drill with a conventional drill, the process will be lengthy and ineffective, since the edge of the drill will not be able to catch on internal structure bricks This may result in overheating of the tool and breakage of the drill.
In addition to using electrical equipment, it is possible to use hand tools, - the so-called bolt. It is a pipe with teeth at the end, with which a hole is made by applying human physical force.
In addition, you will need the following tools:
- Drills or drills
To drill holes in brick wall was effective, it is necessary to use drills with a certain diameter made of carbide material. Their difference from conventional ones is the presence of a diamond or pobedit cutting edge. For hole depths up to 15 cm, you can use drills with a diameter of 0.6 or 0.8 cm. The maximum diameter of the hole that can be drilled into a brick with drills is 1.5 cm.
Pobedite drill bit for brick walls
If you need to drill through hole much larger diameter, it is better to use a drill that is installed on a rotary hammer and impact drill. The size of the drill depends on the depth of the hole. If it is necessary to drill a hole in a wall with a width of 60 cm or more, to speed up the process and its efficiency, it is recommended to use drills of the same diameter, but of different lengths at different stages of drilling, for example, start with a drill 15 cm long, and at the final stage - 50 cm long .
The maximum diameter of the drill hole can reach 2.8 cm.
- Drill bits
To install boxes for sockets and switches, you need to create a niche. In this case, drill bits are used, which are made of durable steel and allow you to obtain large-diameter holes. Drilling with crowns is carried out without the use of an impact function, and their choice depends on the diameter and number of teeth.

Drilling technology
There are three ways to drill a hole in a brick wall: manual, electromechanical and automatic.
However, before starting work, it is necessary to study the location of the electrical wiring, since accidentally touching the wiring line will not only damage it, but can also electrocute a person. Most often, electrical wiring is located vertically or diagonally relative to sockets and switches. If you have any doubts, you should use a special device for detecting wires. hidden wiring. A portable metal detector will help you detect aluminum wire or copper, located no deeper than 1 cm.
A portable metal detector will help detect hidden communications Hand Drilling Technology
With absence electric tool Drilling holes can be done using a bolt. To do this, locations are pre-marked by drilling with a punch. After this, the bolt, which is applied to the wall at an angle of 90 degrees, is struck with a hammer. Every three blows, the bolt is rotated, and the remaining bricks are removed from the pipe. Thus, the hole is knocked out until it reaches the required depth.
Electromechanical process
Mechanical drilling is performed with a hammer drill or hammer drill, the process is the same.
First you need to decide on the type (through, not through), depth and diameter of the hole. This is necessary for a properly selected drill or drill. If you have difficulty maintaining the same distance between the holes, you can use a template. The stencil is made from plywood, chipboard, plastic and other available materials. To use it, you need to fix sandpaper on one side on double sided tape or glue, then lean it against the wall and drill.
After the type and diameter of the future hole has been determined, markings should be made with a core. The drilling process will be easier if it is done in the seam between the bricks. Notches with a core are made in order to fix the drill and facilitate its entry. When drilling with a drill, the tool must be held perpendicular to the wall, pressing gently on it so as not to break the drill or drill. Periodically, the drill must be taken out for cooling in a container with cold water.
If it is necessary to drill a hole with a diameter greater than 18 cm, use a hammer drill with diamond crowns. If these are not available, you can use Victory drills of regular diameter. For this:
- The location of the future hole is outlined, and its outline is outlined with a pencil.
- Drilling is done along the outside of the line; the number of holes depends on the diameter of the contour. The diameter of the drill itself should be 0.8-1.0 cm, the pitch of the holes along the contour should be 1.0 cm. To do the job more accurately, you can use drills with an even smaller diameter, but then the process will take longer.
- Using a chisel and hammer, a sample is made from the drilled contour.
If you need to drill through a thick wall, you can do this in two stages: first, perform the drilling process as described above on one side of the wall. Then, the center of the resulting hole is drilled through. After this, markings are made on the other side of the wall around the intended through center required diameter, the process is repeated.
Automatic process
Diamond drilling is carried out using professional, expensive equipment. In this case, it is desirable to have special skills and qualifications. With the help of such a tool, the drilling process is fast, accurate, almost silent, and can be done at different angles to a depth of up to 40 cm, resulting in a smooth hole, without chips or cracks. This method does not create a lot of dust and dirt, since the tool is equipped with an attachment to cool the drill and wash away the dust.
Drilling in concrete is very difficult, as anyone who has had to deal with a similar problem will tell you. To adequately overcome the resistance of a resistant material, you need to know some of the features of concrete drilling, plus be able to apply knowledge in practice. So, let's find out how to get out of the situation without any problems.
Which drill to drill concrete
To drill a concrete wall, craftsmen use drills with a Pobedit tip.
A simple drill will not cope with such a task. If you need to make a small hole (less than 13 mm in diameter), then a drill is used, and in other cases, a hammer drill. It is significantly more productive than a drill due to the presence of a device with an impact function and a higher drilling speed. When a hammer drill is not at hand, then regular drill with a drill made of carbide with asymmetric sharpening.
Before starting work, it is necessary to mark the drilling location with a core. It is also advisable to minimize the spread of dust throughout the room by attaching a simple device to the hammer drill chuck - a cap made of tin can. Most of the dust will settle there. In order for the plastic dowel to fit fully into the hole made, experts recommend making the recess a centimeter longer than the size of the fastening element itself.
During rotation in concrete, the drill heats up due to friction, which leads to a decrease in its working properties, so the drill is periodically moistened in machine oil or ordinary water.
For high-quality drilling, it is preferable to choose a tool equipped with building level. If such a thing is not provided in the hammer drill, it doesn’t matter; an ordinary small level secured to the body with electrical tape will do.
It happens that you need to drill through concrete, but the drill at hand is too short. Then with inside a blind hole is drilled along the entire length of the existing drill, and a magnet is placed in the resulting socket. WITH reverse side Using another magnet, the location of the first one is determined and drilled at the intended point.
If metal reinforcement interferes with drilling, then change the concrete drill to one that is designed for working with metal. After which they continue with the same drill.
Before drilling into a concrete wall, you should make sure that penetration into the material will not damage any communications.
Using a hammer drill to make holes is considered obsolete. However, for small volumes of work it is indispensable due to its affordability. It is used for drilling by impact or in the usual way. But this method has a significant drawback: during operation, vibrations that inevitably arise from the “slotting” of the tool lead to unwanted defects in the finish. And if, in addition, the hammer drill is very powerful, then the consequences of the actions for the structure are simply unpredictable. To reduce vibrations, new modifications of modern rotary hammers have been developed.
Nowadays, diamond drilling equipment is used more often, especially in large-scale construction - the holes in concrete are smooth and clear, while the drilling machine creates virtually no noise and produces almost no dust and debris. The non-impact method does not cause chips, and it is also possible to avoid the formation of cracks in concrete. And the main advantage of diamond drilling is that in addition to quickly drilling through concrete, it can easily cope with reinforcement.
To make holes in thin concrete partitions, a punch is used: it is made from an 8-millimeter drill, the end of which is sharpened into a “swallow’s tail.” The drill needs to be turned and hit with a hammer.
When drilling in the ceiling, to prevent concrete crumbs from falling into your eyes, it is recommended to attach a protective funnel to the tool.
To secure the screw in concrete, a piece of nylon is driven into the hole. Then they lightly melt it with hot metal (nail), after which the screw is screwed in. The nylon hardens and holds the mount firmly.
A dowel can be replaced by a piece of copper or aluminum tube. It is crimped to the required size, inserted into the hole and screwed.
